Using GIS and Geostatistical Techniques to Identify Neanderthal Campsites at archaeolevel Ob at Abric Romaní

Abstract Although intra-site spatial approaches are considered a key factor when interpreting archaeological assemblages, these often based on descriptive, qualitative, and subjective observations. Currently, within the framework of research into taphonomy palimpsest dissection, several studies have begun to employ more quantitative objective techniques, implementing tools such as geostatistics geographic information system (GIS) methods. This is precisely approach that Abric Romaní team following. In this work, we present GIS methods applied faunal lithic assemblages from archaeolevel Ob, including an analysis structure, identification clusters sectors, size fabric analyses, projection vertical profiles, reconstruction digital elevation model paleosurface. The results obtained indicate clustered distribution, primarily concentrated four dense accumulations. predominance remains < 3 cm in length absence preferential orientations make it possible rule out generalised postdepositional movement affecting most site, although some local has been identified. horizontal analyses allow us identify accumulations single material (lithic or faunal) addition mixed faunal). Integrating all data with previous (zooarchaeological, refits, combustion structures, partial technological analyses), evaluate combine interpretations proposed previously using different approaches, thereby improving overall interpretation Ob. Finally, also develop preliminary comparison between Ob other levels at same site (in particular M P).
